Unemployed is B23025_005 ÷ B23025_003 (unemployed ÷ civilian labour force, age 16 and over); broadband is B28002_004 ÷ B28002_001 (households with broadband of any type ÷ all households) — both worked out here from the two published counts shown beside them. A dash means the Bureau published no estimate. Population carries no ± because the Bureau controls county totals to its official population estimates and publishes no margin for them.
